Abstract
A system that incorporates teachings of the subject disclosure may include, for example, a method for analyzing a wide frequency band with respect to signal power levels in specified narrow frequency bands, detecting narrow band signal power levels received in the specified narrow frequency bands, determining an average composite wideband power level from the narrow band signal power levels, determining an adaptive threshold, detecting narrow band interference according to one of the average composite wideband power level, the adaptive threshold, or both, prioritizing the detected narrow band interference, and selectively filtering a portion of the detected narrow band interference according to the prioritization. Other embodiments are disclosed.
